Using Traffic To Generate Electricity

Leave it up to young students to transform a traffic intersection into an energy source. It’s too bad our politicians cannot think this far out of the box! Piezoelectric plates (the word piezoelectricity means electricity resulting from pressure ) laid under walkways and the road capture the movement and vibrations of pedestrians and cars passing over them, converting that energy into electricity that can then be used to power almost anything in the vicinity. Imagine if these were laid under every major city in the United States; how much electricity could that generate with all the traffic on every street?
